ST. LOUIS, MISEOURI LUBRICATING DEVICE Application filed July 27,

My invention relates to lubricating devices, and more particularly to means for automatically lubricating the valve stems and upper cylinder surfaces of internal combustion engines.

The object of my invention is the provision of a device for supplying small quantities of special lubricant from a container to the intake manifold of an internal combustion engine, so that the flow of combustible mixture of gas and air through the intake manifold passing the valves and into the combustion chambers of the engine cylinders will carry therewith the desired quantities ofvaporized lubricant for automatically lubricating said engine parts.

A further object of the invention is the provision of a supporting bracket to which the container having the lubricant can be readily attached, and when the container is empty, can be readily removed and a new container filled with lubricant quickly attached to said bracket.

A further object of the invention resides in the provision of a conduit leading from he bracket to and having connection with the intake manifold of an internal combustion engine, said conduit being provided with a suitable wick, barely protruding into the intake manifold at one end and extending through and beyond the bracket at its opposite end so that it can be submerged in a depending statein the lubricant of a container which is suspended from said bracket.

A further object of the invention is to provide a wick which is larger in body size than that portion of the wickreceivable in he conduit.

A still further object of the invention is the provision of a conduit having a coil formed intermediate its ends.

A still further object of the invention is the provision of a lubricating device which possesses advantages in points of simplicity and efficiency, and, at the same time proves itself comparatively inexpensive in cost of manufacture.

With the above and similar objects in view, the invention consists in the novel arrangement, construction and combination of parts 1932. Serial No. 624,999.

hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawing forming a part of this specification,wherein like characters of reference denote similar parts tl'iroughoutthe several views:

Fig. 1 is a view partly in side elevation'and partly in section showing the lubricating device embodying the features of my invention.

Fig. 2 is a detail showing the end of the lubricant feed wick communicating with the interior ofthe intake manifold as bound by suitable windings to condense the wick material.

Referrin to the drawing, the reference character A designates a suitable support, such for instance as the dash, or similar support of an automobile, aeroplane, motor boat, or the like, while the reference character 13 designates an intake manifold, onlya portion of which is shown.

In carrying out the aim of my invention, I employ a suitablebracket which embodies a suitable head 1, from which laterally eX- tends an arm 2 provided with a foot 3 directed from either side thereof, and which foot is provided with openings at through which suitable fastening devices 5 pass for securing the bracket to the support A.

'lhe bracket head 1 is shown as provided so with a suitable passage 6 which communicates at its lower, or inlet end with an enlarged vertically disposed internally screw threaded recess 7. 7 Y

A suitable conduit 8, such as copper tuban opening 11 in the wall of the manifold B. The location of the fitting 10 is preferably midway the ends of the intake manifold.

The conduit 8 is preferably, although not necessarily provided with a depending loop,

The opposite 90 or coiled section 12 intermediate its ends. The loop is preferably formed in a horizontally disposed section of the conduit.

A suitable fibrous wick, such for instance, as a woolen wick is employed and that por tion of the wickdesignated 13 is carried by, or receivable in the conduit 8 and its fittings 9 and 10. The outlet end of the wick passing through fittin 10 is preferably, although not necessarily bound with thread, or like binding material 14 so as to condense the material adjacent the fitting 10. "he outlet end of the wick preferably protrudes beyond the outlet end of the fitting 10 and enters the passage 15 of the intake manifold 13 so that the rapid movement of the combustible mixture passed the protruding end of the wick will have a tendency to wipe lubricant therefrom in uniform quantity to be carried with the combustible mixture entering the engine cylinders, as is manifest.

The wick 13 passes through the bracket head opening 6 and the remaining portion of the wick which is designated 16, depends from the bracket head passage (3. This portionlG of the wick is preferably larger in diameter than portion 13 thereof to provide a rapid feed to wick portion 13.

The wick portion, or section 16 depends from the bracket head 1 and is receivable in a container C which is supplied with a suitable lubricant 17. This latter portion of the wick is of sul'licient length to lie. on the bottom of the container so that a sufficient length of the wick will always be thoroughly saturated with luln'icant even when the con tainer becomes nearly empty.

The container C is provided with a suitable screw threaded neck 18 which has screw threaded connection with the screw threaded recess 7 of the bracket head 1 and a suitable packing having a'wick opening 19 is disposed between the open end of the container neck and the base of the recess 7 so as to prevent leakage between the container neck and the bracket recess 7.

The container is readily detachable from the bracket head 1 and assumes a vertical suspended or hanging position relative to the bracket head 1. hen the screw threaded. container neck 18 has been turned into a tight home position in the screw threaded recess 7, the container is securely held against accidental rotation and will not become loose in its connection with the bracket head 1, except by manual force being applied to the can body.

From the foregoing description, read in connection with the drawing, it is apparent, that the suction exerted through the intake manifold and flexible conduit with the wick therein creates a vacuum in the conduit bracket head passage and the container and together with the heat developed by the engine when running, assists the movement of lubricant along the wick from the container, which, when it reaches the outlet end of the wick is wiped or carried oil" the outletend of the wick to be mixed and carried along with the combustible miXturc into the upper ends of the engine cylinders, thereby lubricating all engine parts in Contact therewith in its travel to and into the engine cylinders from the intake manifold.

The many advantages of the herein described invcntion will readily suggest themselves to those skilled in the art to which it appertains.

From the foregoing description, it evident that a simple device for this purpose has been disclosed, but it is to be understood that I do not desire to restrict, or limit myself to the very details of the construction shown and described, which is merely illustrative. it being obvious that changes. not involv ing the exercise of invention, may be made without conflicting or departing from the spirit of the invention within the scope of the appended claims.
